have disclosed herein an embodiment oii therein as may he fairly embodied Withinthe spirit and scopeiof the invention as claimed. ,Tiaving thus describedinyinvention, 4What l desire to secure by Letters Patent is:

l. .a muiiler. for the exhaust of internal combustion engines comprising an exhaust A pipe, a housing surrounding said pipe and servingv to close the end thereof, an outlet from said housing, and a baviilein saidyhous" ing and supported byv said pipe, including` a pair of end plates, a plurality'of cylinders of mesh Wire carried by saidplatesand surrounding said pipe, a pluralityl of openings in said pipe on'the lower side thereof, said housing being adapted to be partially filled With liquid whereby sparksv may be extinguished.

2. A muflier for internal combustion engines comprising an exhaust pipe, openings therein, a plurality of cylinders of Wire mesh surrounding said pipe,'discs attached to Asaid pipe and supporting said coils, a housing about said cylinders and adapted tocontain a fluid.

3. A device of the character described comprising a housing adaptedtocontain fluid, an exhaustpipe passing into one. end thereof, a plurality of layers of mesh Wire surrounding said pipe and Within saidhousing Whereby exhaust gases from said pipe'are yconipelled to pass thru said Wire, discs oiisaid pipe to support said layers of vvire, and an outlet fro-in said housing. l

4. ln a inuiier, a housing, an inlet, an outlet, and ineans disposed in the path ofthe gases to cause dispersion thereor" before said outlet is reached, said means includinga plurality of `layers `of fabricated Wire `mesh and discs to support said layers in concentric relation, said inlet discharging in adirection opposed to that of said outlet'. i i

In a muffler, a housing, a discharge pipe longitudinally of said housing andV having .downwardly directed openingstherein, said outlet above said pipe, discs mounted on said pipe and a tubular section of foraininated material connected with said discs and surrounding said pipe.
